Answer 1

Juma Muyaka
The strcmp() function compares two strings.

strcmp(string1,string2)

Return Value: This function returns:
0 - if the two strings are equal
value<0 - if string1 is less than string2
value>0 - if string1 is greater than string2

echo strcmp("Hello","Hello");
output= 0
equal

echo strcmp("Hello","hELLo");

output=-32
as ASCII Code for H =71
and ASCII code for h = 104
result = 71-104=-32
